MIXING DEVICE FOR INTERNAL-COMBUSTION ENGINES.

Application filed November 10, 1921. Serial No. 514,303

To all whom it may concern:

Be it known that I, MICHAEL S. MONKS, a citizen of the United States, residing at Pittsfield, in the county of Berkshire and State of Massachusetts, have invented certain new and useful Improvements in Mixing Devices for Internal-Combustion Engines, ofwhich the following is a specification.

This invention relates to mixing or atomizing devices for internal combustion engines.

I The object of the invention is to provide a simplyconstructed device adapted for insertion intermediate the carbureter and the intake manifold of an internal combustion engine which will materially assist in the thorough atomizing and commingling of the gaseous vapors from the carbureter.

Another object is toprovide a simple device of this character which may be readily inserted at the joint where the intake manifold joins the carbureter without any change being made in either, the only difference being that the bolts which connect these two members are removed and the device constituting this invention inserted between the flanges of the intake manifold in the carbureter and secured by longer bolts than those which connected the former.

With these and other objects in view, the invention consists in certain novel features of construction as hereinafter shown, described and claimed.

In the accompanying drawings, wherein like numerals designate like parts throughout Figure 1 represents a perspective view of an internal combustion engine showing this improved device inserted between the carburetor and the intake manifold thereof,

Fig. 2 is a plan view of the attachment detached,

Fig. 3 is a longitudinal section taken on the line 33 of Fig. 2.

Fig. 4 is a plan view of the attachment showing a slightly different form, and

Fig. 5 is a transverse section thereof.

In the embodiment illustrated, an intake manifold I of an internal combustion engine E is shown to the lower end of which the carbureter C is usually bolted each of these members being flanged as shown at F and are connected by bolts B in the usual manner. The device constituting this invention as shown in Figs. 2 and 3 comprises a substantially ovate plate 1 preferably composed of aluminum and provided with a central aperture 2. The aperture 2 has a shoulder 3 adjacent one face of the plate 1 to support a retaining ring 4: which is provided and inserted in the groove for the purpose of preventing accidental removal or displacement of a screen 5 which is fitted in the aperture 2. This screen 5 is curved in the direction of the passage of the gas when the plate 1 is in its proper position between the carburetor and the manifold and this curved form of screen is found to be the most efficient for use in commingling or atomizing the gases.

Arranged in the screen withinv the aperture 2 is the atomizing device 10 constituting the gist of this invention and which is made in the form of a coiled flat metal spring similar to the main spring of a clock and being disposed edgewise to the entrance of the gases to the manifold operates to breakup the globules in the gasolene and converts it into spray causing it to mix readily with the air and pass through the manifold in the form of vapor into and through the intake and into the cylinders. It will of course be understood that this atomizing of the gasolene on its entrance to the intake manifold will not only greatly increase the power and speed of the engine, but Will effect a saving of from twenty-five to forty per cent in gasolene.

As shown this helical spring 10 is arranged in the aperture 2 at the end opposite to that in which the ring a is disposed but obviously it may be mounted at any point Within the aperture and may be held in any suitable manner being here shown held by friction.

This atomizing device 1 may be constructed as an article of manufacture and sold as an accessory for internal combustion engines being. applicable by any unskilled workman since the only thing to be done is to remove the bolts which fasten theflanges of the intake manifold and the carbureter, place the device between them with the fiat face openings 6 and 7 in the ends of plate 1 to register with the bolt holes in the flanges F and then apply the bolts B and screw them up and the device is ready for use without requiring any adjustment whatever except of course to adjust the carburetor so that less gas will be fed. It is of course understood that the usual gasket is placed between the platei and the fl'anges F suchas is ordinarily used when this attachment is not-employed.

In the operation vof this device the gases drawn from the carbureter by the suction of the engine are caused to-circulate between what may be termed a priming chamber 12 therein into Which the gas Which condenses on the stoppage of the engine flows through anc'paperture 11 in each coil of the spring 10 and is retained so that When the engine is again started the gas in said chamber is drawn back through the apertures 11 in the spring and increases the richness of the mixture thereby materially assisting in starting the engine.

The preferred embodiment of the invention is disclosed in the'dravvi'ngs and set forth in the specification, but it Will be understood that anymodific'ations within the scope of the claimed invention may be made in the construction Without departing from the principle of the invention or sacrificing any of its advantages, T

An atomizing device for internal "c0mbu's-' tion engines comprising a plate for insertion intermediate the carbureter and intake manifold of the engine, said plate having an aperture to register with the 'c'arbureter opening and the manifold, one Wall of said aperture having a priming chamber to receive and retain condensed gas, and a -helical flat metal spring mounted in said aperture and arranged 'edgewise With'the edges in the direction of the flow of the gases, said spring having an opening for the passage of the condensed gas.
